PURPOSE: A cooling structure of an LCD projector is provided to lower an operating temperature of RGB and to fabricate a compact LCD projector by removing heat in an optical passage through attaching a thermo-electric module to the optical passage. CONSTITUTION: An LCD projector cooling structure includes a cabinet(21), and a lamp(22) installed in the cabinet(21) in order to radiate light. A plurality of total reflection mirrors(25,26,27) and dichroic mirrors(23,24) are provided to reflect light radiated from the lamp(22). Light reflected from the total reflection mirrors(25,26,27) and dichroic mirrors(23,24) is incident into RGB panels(28,29,30). A lens(33) is provided to project light incident into the RGB panel to a screen. An optical path is formed between the lamp(22) and the RGB panels(28,29,30). A thermo-electric module(41) is attached to the optical path so as to transfer internal heat to an exterior. |
